Ajax NetworkError：发生网络错误 [英] Ajax NetworkError: A network error occurred

问题描述

就在昨天，这个代码在我的LAMP中启动并运行，我不确定是否可以造成任何重大变化。这是一个简单的ajax脚本，可以从API中检索数据。

Just yesterday this code was up and running in my LAMP, I'm not sure if I could inflict any major changes. It's a simple ajax script that retrieves data from API.

今天它停止了工作，控制台只是抛出NetworkError：发生网络错误。，甚至更奇怪的是，我自己尝试了格式化的GET查询，一切正常，API响应正确。

Today it stopped work, the console just throws "NetworkError: A network error occurred.", even stranger is that when I tried the formatted GET query myself it all worked fine, API responded correctly.

http://localhost/uzduotis2/data/mobile/api/mobile.php?query%5Boperators%5D%5B0%5D=1&query%5Boperators%5D%5B1%5D=2&query%5Boperators%5D%5B2%5D=3&query%5Bmin%5D=180&query%5Bsms%5D=400&query%5Bmb%5D=128&query%5Bperks%5D=7&_=1385898696657

好吧，我不知道还能做些什么 - 也许有办法让错误代码更具体？...无论如何，这里是代码：

Well, I don't know what else I can do—maybe there was a way to make the error code more specific?... Anyway, here's the code:

function ajaxCall(url, req, req_type, async) {

    return jQuery.ajax({
        type: req_type,
        url: url,
        data: req,
        contentType: "charset=utf-8",
        dataType: 'json',
        timeout: 30000,
        async: async,
        cache: false,
    });

}

 var ApiUrl = "http://localhost/uzduotis2/data/mobile/api/mobile.php";

$(document).ready(function() {

// .....

        var req = {query: {operators: Operators, min: Min, sms: Sms, mb: Mb, perks:Perks}};
        var promise = ajaxCall(ApiUrl, req, 'GET', false);

        promise.success(function(out) {
            console.log(out);
//            populate(out);
        });

        promise.error(function(out){
            console.log(out);
        });
}

编辑

我刚发现它适用于其他浏览器，必须是缓存相关问题，也许有人知道可能是什么？

I just found out that it works on another browser, must be a cache related issue, maybe somebody knows what could it be?

推荐答案

您必须以异步方式返回数据，因此必须将async设置为 true

you must return data in asynchrounous way so you must set async to true

var promise = ajaxCall(ApiUrl, req, 'GET', true);
